Teach Engineering: Discovering Friction
With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to...
Texas Education Agency
Texas Gateway: What Is Force?
You have probably heard the word "force" before in conversations. Here are a few examples: "the rocket had a lot of force at blast off" or "the force of the storm blew the roof off the building." What is force? Force is defined as a push...
